Procedure
4-{[6-Chloro-4-(1-trifluoromethyl-cyclopropylamino)-pyrido[3,2-d]pyrimidin-2-ylamino]-methyl}benzenesulfonamide (0.100 g, 0.23 mmol) was combined with 2-(3-methanesulfonyl-4-methoxy-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (0.091 g, 0.34 mmol, see Scheme 7), palladium tetrakistriphenylphosphine (0.013 g, 0.011 mmol) and sodium bicarbonate (1.5 mL of a saturated aqueous solution). The mixture was suspended in DME (3 mL) and heated to 65° C. for 1 h. Crude product was precipitated by the addition of water (5 mL). The precipitate was filtered and purified by reverse phase HPLC (5-100% ACN/H2O+0.1% TFA) to give 0.056 g (40% yield) of the title compound, and was characterized by its NMR and mass spectrum as follows: 1H NMR (d6-DMSO): d 1.38-1.26 (m, 4H), 3.31 (s, 3H), 4.06 (s, 3H), 4.79 (m, 2H), 7.34 (s, 2H), 7.46 (d, J=8.7 Hz, 1H), 7.55 (d, J=8.4 Hz, 2H), 7.78 (d, J=8.4 Hz, 2H), 8.01 (d, J=9.0 Hz, 1H), 8.45-8.41 (m, 2H), 8.90 (d, J=11.4 Hz, 1H), 9.08 (bs, 1H), 10.15 (bs, 1H): MS (m/z): 623.2 ([M+H]+, 100).
